I moved into a new build house four years ago. Half the development has FTTC, half can’t get it. I’m in the poor half 
The exchange is literally at the top of my street and has been upgraded for fibre. There are two cabinets serving the development, one of which has been upgraded. The other, which I’m connected to, hasn’t been upgraded and Openreach have no intention of upgrading it in the foreseeable future. I’ve written to Openreach several times, I’ve even written to my MP. (Surprisingly, she investigated with Taylor Wimpey, Openreach and the local council, though nothing positive came of it.)
I had an ADSL connection when I moved in but it was so unreliable that I got rid of it in favour of 4G. That was great at first - speeds of around 60Mbps down / 30Mbps up. As more people have caught on, the service has degraded to the point where it’s as bad as my old ADSL connection.
I recently signed up for ADSL again and bought a load balancing router. I now use both my ADSL and 4G connections, with traffic split between them. When one goes down, everything routes over the other connection. Speeds are similarly poor, though I don’t completely lose connectivity as often. (I have still experienced both connections going down at the same time on the odd occasion.)
I’ve now discovered that a private company called YouFibre are bringing FTTP to the area. I checked on their website and was able to pre-order a 1Gbps FTTP connection. They start taking pre-orders when work begins in the area, with a view to services being ready to go in around 6 months. The usual price is £50/month, which I’m more than happy with for 1Gbps! However, they have an early bird discount of 25% for the first 18 months, so that becomes £37.50. When I placed the pre-order, they gave me a further 10% discount. That means I’ll be paying £33.75 a month 
I’ve really struggled working from home with the poor connectivity, so I’m delighted this upgrade is on the way.
